IMPROVEMENTIN MACHINES FOR CUTTING FABRICS.

Specification forming part of Letters Patent No. 197,901, dated December 4, 1877, application filed May 7, 12577.

- anduseful Improvements in Machines for Outting Fabrics, of which the following is a full,

clear, and exact description, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Figure 1 is a perspective view of my improved fabric-holder, the same being shown as opened to receive the fabric to be cut; and Fig. 2 is a cross-section thereof, the parts being closed down, one upon the other, and the fabric being omitted. Fig. 3 is an elevation of the cutter complete and ready for use. Fig. 4. is a similar View, showingthe knife with its several blades, the cap or plate being removed; and Fig. 5 is an elevation of the detached cap or plate.

Like letters in all the figures refer to corresponding parts. The object of my invention is to provide a simple and comparatively inexpensive apparatus for holding and cutting fabrics, such as cloth, carpets, silk, felt, and the like 5 and to this end it (the invention) consists in certain novel arrangements and combinations of parts, as will be hereinafter fully described, and then A is the bed or base of the holding implement, upon which the material to be cut is clamped by means of the plate B, hinged at one end to the base, as at O. The plate B has a central longitudinal slot, a b, the lower portion of which, a, permits the passage of the cutt'm g-knife through to the fabric, and the upper enlarged portion 12 serves as a guide for the casing of said knife, as will hereinafter appear.

In order that the fabric may be firmly held in proper position for cutting, the plate B is provided with two rubber or other strips, 0, running parallel with, and one upon each side of, the slot to, which strips force the fabric down upon the cutting-block (2, attached to the base, and intended to receive the impress of the knife. When the two parts A and B are closed together upon the fabric it isobvious that it will be securely held, and that the drawing of the cuttingblade through the slot at will not ravel the goods, as would be liable to be done without the use of some clamps uponeach side of the line through which the cut is to be made.

These clamps press the goods down upon the attached to the upper face of the plate B, for

convenience in making such measurements as may be desired during the use of the implement, or at other times.

I In the side of the plate B are hinged a couple of measures, -E E, the purposes of which are to gage the ainoimt of material to be cut off fiom the main piece. They are graduated from the hinge outwardly, and, when located at right angles to the edge of plate B, will serve to indicate the length of the piece of cloth projecting beyond the knifeslot a. When not in use they are closed down and rest within a suitable recess provided for their reception.

The knife or cutter intended to be used in in gperforated to receive the stop-screw 0. The I space between the several cutting parts of the aXled blade is so graduated as that when any particular one is turned downwardly and held in place by the stop-screw 0, those next adjacent will not project sufficiently below the curved surface 9 to reach the cloth or fabric which is held in the clamp A B.

The cap F is easily removed by turning out screw 0, whereupon the knife. or cutter maybe taken out and ground, as'occasion may require.

The cloth to be out being suitably clamped and held, the cutter is moved along in the slot provided for it, either toward or from the operator, in a manner easily understood from the drawing. If the goods be considerably less in width than the guide is long, the blade u, having the greatest curvature, may be most advanrequired, and. the upper face of the clamp Bis cut away, as at b b, to afford room for so much of the blade-casingas may project beyond the I blade on either side.

As thus constructed and arranged, the device is easily operated, and is found to admirably answer the objects of the invention, as before stated.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. In an implement for holding fabrics to be cut, the combination, with the base thereof,

which has a raised longitudinal strip to receive the impress of the cutting-blade, of a slotted clamping-plate hinged to said base at one end, and adapted to hold the goods upon both sides of said longitudinal strip, substantially as and for the purposes set forth.

2. In combination with a slotted clampingplate hinged at one end to a suitable base, and adapted to'hold a fabric to be cut, in the manner specified, a gage or rule hinged to said plate at one side thereof, and serving to meas- Inc the length of the piece to be detached, substantially as shown and described.

3. In combination with the herein-described casing for a fabric-cutter, a series of cuttingblocks aXled within said casing, and adapted to be removed or clamped in place for use, in the manner and by means substantially such as herein specified.

DAVID P. SARGENT.
